This Catcherman is nowhere near the oldest, but easily the most worn. Most of the wear happened in about a 5-year span, 2012-2017, when I was fishing a lot but didn't have many knives. During that span I seldom cleaned or sharpened it, just left it in the ice chest til the next trip. A few years ago I cleaned it up for this photo, which I've posted several times. Action is still smooth, and of course it cuts like a laser.
